Installation for producing a medical preparation

Abstract

The invention relates to an installation for producing a medical preparation, in particular for producing a preparation for parenteral nutrition. Liquids are transferred by means of the installation from a plurality of source containers to a target container. The installation comprises a receptacle with drivers for a valve block, wherein the drivers of the valves are arranged offset from one another.

The invention claimed is: 
     
       1. An installation for producing a medical preparation, by way of which liquids from a plurality of source containers are transferable into a target container,
 wherein the installation comprises 
 at least one pump and 
 a receptacle for a removable valve block having a multiplicity of valves, 
 wherein an inflow from the source containers is controllable by the valves, 
 wherein the valves comprise activation members, 
 wherein the installation has entrainment elements that activate the activation members to open and close the valves, and 
 wherein the entrainment elements are disposed so as to be mutually offset in at least two rows according to the principle of the hexagonally tightest pack so as to be mutually spaced apart. 
 
     
     
       2. The installation as claimed in  claim 1 , wherein the entrainment elements are disposed in at least two straight rows, wherein the entrainment elements in one row are offset by approximately half of the respective spacing of said entrainment elements in relation to the entrainment elements of the other row. 
     
     
       3. The installation as claimed in  claim 1 , wherein the installation comprises a drive unit having motors for the entrainment elements, wherein the motors are disposed in at least two mutually displaced rows. 
     
     
       4. The installation as claimed in  claim 3 , wherein the motors comprise housings, wherein the housings of the motors along the rows are disposed so as to be mutually engaging. 
     
     
       5. The installation as claimed in  claim 1 , wherein the entrainment elements for driving the valves are connected to drive shafts of the motors by way of drive shafts that run in a linear manner. 
     
     
       6. The installation as claimed in  claim 1 , wherein the entrainment elements are connected to the motors by way of dog clutches. 
     
     
       7. The installation as claimed in  claim 1 , wherein the installation comprises a modular drive unit for the entrainment elements, said drive unit being attached to a side of a housing of the installation that is opposite the entrainment elements. 
     
     
       8. The installation as claimed in  claim 3 , wherein the motors of the installation are monitored for load. 
     
     
       9. The installation as claimed in  claim 1 , wherein the installation comprises a sensor unit for monitoring the respective valve position. 
     
     
       10. A valve block for placing onto an installation for producing a medical preparation as claimed in  claim 1 . 
     
     
       11. The valve block as claimed in  claim 10 , wherein the valves have in each case one outlet to a catchment duct, wherein the outlets of all valves along the catchment duct are disposed so as to be mutually spaced apart in an axial direction of the catchment duct. 
     
     
       12. The valve block as claimed in  claim 10 , wherein the valves are configured as 3/3-way valves having a blocked central position. 
     
     
       13. The installation as claimed in  claim 1 , wherein the activation members comprise plugs. 
     
     
       14. The installation as claimed in  claim 2 , wherein each of the valves has an outlet that leads to a catchment duct that defines an axial direction along which the outlets are mutually spaced apart. 
     
     
       15. The installation as claimed in  claim 9 , wherein the sensor unit comprises a plurality of light barriers into which, depending on the valve position, a finger reaches. 
     
     
       16. An installation for producing a medical preparation, by way of which liquids from a plurality of source containers are transferable into a target container, wherein the installation comprises at least one pump and a receptacle for a removable valve block having a multiplicity of valves, wherein an inflow from the source containers is controllable by the valves, and wherein the valves comprise activation members, wherein the installation has entrainment elements by way of which the valves are activatable, wherein the entrainment elements are disposed so as to be mutually offset in at least two rows wherein the entrainment elements are movable by way of the drive shafts, wherein a front portion of the drive shafts is mounted in a level of a drive unit that is disposed above the dog clutches. 
     
     
       17. An installation for producing a medical preparation, by way of which liquids from a plurality of source containers are transferable into a target container, wherein the installation comprises at least one pump and a receptacle for a removable valve block having a multiplicity of valves, wherein an inflow from the source containers is controllable by the valves, and wherein the valves comprise activation members, wherein the installation has entrainment elements by way of which the valves are activatable, wherein the entrainment elements are disposed so as to be mutually offset in at least two rows, wherein the installation comprises a sensor unit for monitoring the respective valve position, wherein the sensor unit comprises a plurality of light barriers into which, depending on the valve position, a finger reaches. 
     
     
       18. The installation as claimed in  claim 17 , wherein the installation comprises a plurality of sensor units, wherein the sensor units are disposed on the upper side of a support as well as on the lower side of a support, in particular of a printed circuit board.
